[Bug 1942427] Re: [Lenovo Thunderbolt 3 Dock] Upgrade to 5.11.0-31-generic #33 breaks use of external displays with i915
Update: after upgrading to 21.10 (Linux 5.13.0-21-generic #21-Ubuntu SMP Tue Oct 19 08:59:28 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux) the problem persists with a twist: The settings applet now sees all monitors, but trying to configure a setup with all three is not really feasible since selecting a setup leads to both external monitors going blank and the primary screen dimming, with no visible dialog for confirming that the new configuration is to be applied permanently (possibly displayed on one of the two blanked-out monitors). I hope this bug will be addressed shortly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942427 Title: [Lenovo Thunderbolt 3 Dock] Upgrade to 5.11.0-31-generic #33 breaks use of external displays with i915 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1942427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The last working kernel version was indeed the kind of information the developers were looking for.

I'm a bit of a Linux n00b so I don't know what type of troubleshooting detail/information would be of any use, but I'm experiencing the same thing. Been struggling for a few weeks/months and tonight decided to try and use Advanced Mode at the boot up screen and chose to launch with an older Kernel, and my VGA-connected screen came to life again. So specifically this kernel version works perfect: Linux 5.11.0-25-generic And for this one, there's absolutely no way to get my third monitor, connected via VGA port, to work: Linux 5.11.0-31-generic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942427 Title: [Lenovo Thunderbolt 3 Dock] Upgrade to 5.11.0-31-generic #33 breaks use of external displays with i915 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1942427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The system now runs 5.11.0-34-generic which still has the bug. Looking in my /boot the oldest I have is 5.11.0-31-generic which introduced the bug as far as I can tell (thanks apt autoremove). I do however update whenever the thing prompts me to so I would venture a guess that whatever preceded 5.11.0-31 worked. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942427 Title: [Lenovo Thunderbolt 3 Dock] Upgrade to 5.11.0-31-generic #33 breaks use of external displays with i915 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1942427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
